Question

2. Power conditioning equipment in the PV system includes (a) Charge controller (b) Inverter (c) MPP tracker (d) Circuit breaker 3. In a PWM inverter, (a) The output waveform can be controlled. (b) The output frequency can be controlled. (c) The output amplitude can be controlled. (d) The output phase angle can be controlled. 4. The balance of the system in a PV system includes (a) Wires (b) Surge protection devices (c) Lightning protection (d) Fuses 5. For the battery storage of 450 Ah at 12Vde, we only have 6V batteries rated at 150 Ah. Thus, we need (a) 2 batteries (b) 4 batteries (c) 6 batteries (d) 8 batteries

Answer 1

2.

Ans :Option (a),(b),(c)

Power conditioning equipment in the P V system is an system which provide us a facility to charge the battery bank

It consist of Solar charger (Charge controller) , M P P T, Inverter, Grid charger , Output selector mechanism, Control algorithm

3.

Ans:Option (a)

Pulse width modulation is the process of modifying the width of pulses in a pulse train in direct proportion to small control signal .In P W M inverter output waveform can be controlled . Fundamental Frequency of output waveform  is same as the input waveform frequency . Frequency of waveform can be control by employing 3 single phase inverter and changing the frequency of input waveform

4.

Ans: Option (a)

The balance of system of P V system consist of components of all photo voltaic system except the photo voltaic panel. It includes wiring , switches , Mounting system ,solar inverters ,Battery bank and battery charger .

5.

Ans: Option (a)

As we need total of !2V and we have 6V batteries we can connect two batteries .
